Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China

open access: yesWildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

The Productivity Advantages of Large Cities with Heterogeneous Firms: Agglomeration, Sorting and Selection [PDF]

open access: yes, 2016
改革开放后的非均衡发展战略使我国城市间产生较大经济差距,我国城市间全要素生产率的差异呈现逐渐扩大的趋势。现有关于城市间生产率差异的研究主要关注大城市的集聚效应,而近年来“新”新经济地理学的发展融合企业异质性,提出了分选效应与自然选择效应,为解析大城市生产率优势提供了新的思路,同时也指出了以往的研究可能高估了集聚的效益。因此探讨分析我国城市间生产率差异的影响机制与内在原因,有助于为寻找解决经济发展中地区不平衡的方案、选择有效且切合实际的政策提供理论建议。 本文在相关研究的基础上,构建了一个包含集聚 ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Functionally diverse stands promote leaf litter decomposition irrespective of litter species' resource acquisition strategy

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Stand functional diversity (RaoQ) and stand functional composition in terms of the functional traits of the component species (CWM trait) are critical for ecosystem processes and functioning, such as litter decomposition and associated nutrient cycling.

One‐Sidedness and the Inferior Function in Coriolanus and Timon of Athens

open access: yesJournal of Analytical Psychology, EarlyView.
Abstract For both Jung and Shakespeare, one‐sidedness is the fundamental tragic trait. Jung proposed that as an individual develops, they inevitably associate their identity with certain modes of perception and interaction, and that this leads to psychological polarization.
